Coalize, there's been a lot of new light lately. Another significant one is that they state they weren't being as discreet as they should have in the past and are dropping all their types and antitype interpretations unless the scriptures indicate clearly that they should apply. Unfortunately they haven't been specific about where the bible clearly indicates this and have only given a few insignificant examples.
Even if a JW was keen enough to keep up to date it is impossible because the GB are not specific enough.
